Development of technology for high-strength cast iron for manufacturing D49 head of cylinder

This article discusses the technology of melting high-strength cast iron with a spheroidal graphite shape intended for D-49 type cylinder lid by modifying magnesium (Mg) in ladle and gating systems. Today, it is very important Republic Uzbekistan CIS countries to create improve production prepare high-responsibility parts railway transport. Improvement mechanical operational properties high strength, as well development improvement casting D49 diesel engine head imported from under local conditions.
